Trowa does not think overmuch on curiosity. (That doesn't mean it's not a frequent factor in his life. Trowa's curiosity is patient, unhurried, and pretty comprehensive.)

The tent containing the cages is in sight, but still several yards away, when a grey-haired woman emerges from her trailer. She has a slight stoop to her shoulders (the only thing marring the upright carriage of an ex-acrobat), and the sort of face that tends to look stern no matter how the person is feeling.

Trowa pauses, waiting for her to spot him in turn.

He doesn't glance at X, because he doesn't need to.
